1 out of 5 eggsFast but unreliable

Pros: If you can get it to work, transfer speeds are quick.

Cons: Will not work without an external AC power supply.
Overheats quickly.

Other Thoughts: I've tried the drive on 2 different desktops and 1 laptop with USB 3.0 ports and none had enough power to get the drive to work. Light would come on, but you could hear the drive spinning at variable speeds and popping in and back out of the computer's drive list.

Adding an external AC supply to the mix got it to power up reliably, but after about an hour of solid data writes (my intended use is a backup 3TB of data), it crapped out and was no longer recognized by the computer.

A few days later, I tried again and the drive was back to working which made me suspicious of temperature issues. This time I loaded some SMART drive monitoring software before trying again. Sure enough, after about 20 minutes, the drive temperature was being reported as 128 Fahrenheit and was still climbing. It's a plastic case (ie a thermal insulator) that just can't get the heat out when under high load.

I had transfer speeds up to ~150MBps, so the drive is fast if you can get it to work, but it can't sustain that rate for more than a few hundred GB of data. If the point is to be able to reliably back up 4TB of data, it fails miserably. Very disappointed in this drive.

1 out of 5 eggsXbox One External Drive

Pros: Fast external drive with no need for an external power adapter.

Cons: Seems to overheat after an hour or so of use and causes my games to stop loading and freeze on my Xbox One. Also, it comes with a USB cable that is only about a foot long.

Other Thoughts: I have tried several basic things to keep the drive cool. I bought a 6 foot long USB 3.0 SS cable for it and moved it away from my Xbox and other sources of heat. Tried elevating the drive about an inch off the surface with just something holding it up at the sides.

If I put and keep a cold ice pack on top of it, I can game and download for hours with no problems, such a hassle though.

1 out of 5 eggsInteresting issues

Pros: 4 TB, decent price, smallish usb drive for 4 TB.

Cons: I have had several issues getting computers to recognize this drive at times. It feels like the drives controller or something gets hung up at times. Occasionally explorer.exe will hang when I plug it in, and then I move it to a usb 3.0 port and it's fine. I was finally able to figure that out and work around it. Although it's not 100%, and I copied ~2 TB of personal data on it and there is a lot of corrupt files? Seems like a similar issue to Christopher c. The files copy over to the drive perfectly fine, and they even have the correct file sizes, I can pull them up in winhex and there is data there, but no metadata for movies for example. So it won't play, VLC basically throws the file up. Without looking too much more, it's like the headers are messed, or something similar.

I've formatted the drive a couple times, and started copying over 2TB a couple times... that takes a while, even over gig ethernet from a NAS box. And it doesn't seem to matter where I copy from, or which computer. The worst part is that HDD scan and seatools for windows both show S.M.A.R.T. as good, and passes short self tests and short generic tests. I started read and verify tests from hdd scan, which were good until I cancelled them (~5%). I'm running a long generic test from seatools now overnight, but it looks like it will pass... Very frustrated with this. Would like to RMA, but can't without a valid failure. No firmware updates either for it.

If you use this drive, please verify the files. As always, test your backups.

5 out of 5 eggsSeagate Backup Plus Fast 4TB

Pros: The Seagate Backup Plus Fast 4TB is an absolutely terrific external portable Hard Drive. Having 2 2TB Hard Drives in Raid-0 has to be the best idea ever for an external portable Hard drive, I was so excited upon receiving The Seagate Backup Plus Fast, this is a truly innovative product. I am going to keep this review somewhat short, The Seagate Backup Plus Fast is very solid and is well constructed and feels of great quality. It contains 2, SAMSUNG Spinpoint M9T ST2000LM003 2TB 5400 RPM 32MB Cache SATA 6.0Gb/s 2.5" with an "Average Seek Time of 12ms" and an "Average Latency of 5.6ms", and all the Reviews I have read regarding these Drives have been terrific, I do not think I seen one bad review.

Cons: I can honestly not think of one bad thing to say about The Seagate Backup Plus Fast 4TB, I think it is a terrific , innovative design and I truly love this product.

Other Thoughts: I did a few tests with The Seagate Backup Plus Fast 4TB, 1st with ATTO Disk Benchmark I received a steady 200 MB/s both Read and Write, and with AIDA64 Disk Benchmark Read Test Suite I received a max transfer speed of 210.9 MB/s and an Average Read Access of 0.00ms! and I was completely enthralled with these results. The price point of The Seagate Backup Plus Fast 4TB is awesome, it is actually cheaper to buy the Backup Plus Fast than to buy the Drives themselves and I think you would have trouble finding a Raid-0 to USB3 adapter, and if so, how much would that cost you. Like I mentioned before this is a terrific and innovative product at a great price point, and you will be very satisfied with The Seagate Backup Plus Fast 4TB.

5 out of 5 eggsFast & Portable

Pros: Nice aluminum case with a small white LED to tell you it's on. The software that is bundled is nice and lets you back up as you go or set a defined time frame for your back ups. You can also just drag and drop your own files as well.

Cons: None

Other Thoughts: I am using this as back ups of my photography. With USB 3.0 and 4TB of storage this should last me a long time.

4 out of 5 eggsNecessary Backup

Pros: - Small Size
- No power brick needed
- Preloaded software has no Bloat ware
- Large Capacity
- Intelligent Run cycle for back
- Fast back up for Mechanical HDD's
- Lots of instructions in many languages.
- Can be converted to regular Mechanical drive if you have the knowledge of computer building

Cons: - None at present

Other Thoughts: Seagate was once THE only Hard disk to buy, their quality was second to NONE. They were the best, hands down. Then Businessmen and accountants started to run the company and the quality dropped terribly as they started eating up other vulnerable and other un reliable companies. Its my opinion that they have learned from their mistakes in the past and their hdd are getting slowly better quality but still not to the Rock Solid standard of the glory years of Seagate.
My first thought was this hard drive cannot breath. Its totally incased inside this plastic prison.
This is not a bad thing as I have noticed that the drive stays in a state of sleep until you activate it for back up and spilling coffee will not kill the drive.
The Speed was 9 minutes for 350GB from my SSD Very fast but my SSD is fast and my X99 with DDR4 is fast too and I used USB 3.0 which is faster than SATA 3. Alas, you are only as fast as your slowest part in computing. That would be this HARD DRIVE in this circumstance. I would recommend this for a primary back up but I would also recommend having an even bigger archive drive array to supplement this one small tool. This is a good product but even the best can break down at some time or other so never put all your eggs in one basket. Put them in several places so your backups are kept for many years to come.

4 out of 5 eggsSo far so good

Pros: Cheapest per Gb costs i've seen for a whiles.

Cons: Way cheaper elsewhere.
Only 2 year warranty :(

Other Thoughts: Some older pc's will not see the whole drive, or the drive at all, so you XP users may have problems - on newer win OS'es i've had no problem (with newer BIOSes for their hardware)
It works under latest Ubuntu desktop OS just fine from my dell vostor laptop!

3 out of 5 eggsNeeds more energy

Pros: Advantage: 4TB and faster

Cons: Disadvantage: More expensive per GB, double size and double weight of a 2TB. Needs more energy, sometimes two cables needs to be used in order to provide energy.

Other Thoughts: The reason giving 3 eggs it's because the price benefit.
For most users this hard drive only will be worth to buy when the price per GB will be cheaper than 2TB.
On Newegg sometimes it's possible to buy for $90 a 2TB HD

1 out of 5 eggsDisappointed

Pros: Was nice until the drive started getting around 80% full.

Cons: Using this as a movie server drive for personal movies and documentaries that I make and share but as soon as it started getting around 80% full many of the movies would randomly turn into folders and were no longer recognized by the PC or media player as a movie file. Thinking it was a glitch I've removed the corrupt files/folders but now more keep showing up. its as if the drive will not accept more files.

Removed drive from case because it shows up as a

Make sure you don't keep valuables on this drive.

Other Thoughts: I do have this device connected through a Cisco router and add/remove file from it over the network. I've really only added files until they started getting corrupted.

Connecting drive directly to the PC and running an error check does not resolve the issue.

Seagate has no troubleshooting help / forum regarding this on their site. Multiple attempts to try and get help has failed.

Thankfully I always backup to the cloud but people on a budget would lose their data.

Looking back, I've had more problems with Seagate than any other brand, might be a coincidence.

I'll update if I can find a fix or Seagate ever calls back.
